Thiem won 85 per cent of points on his first serve and did not face a single break point, while Monfils was unable to hold on four occasions.

Austrian Thiem, winner of this tournament in 2016, will be a strong favourite to claim his ninth ATP World Tour singles title when he takes on Bedene, who beat home favourite Federico Delbonis 6-2 2-6 6-1 in the other semi.

Slovenian Bedene reached his third ATP World Tour showdown after blasting down 15 aces and breaking five times to topple the world number 70.
